SAN LUIS OBISPO, Calif. (AP), Jun 26 - A reactor at the Diablo Canyon nuclear power plant on the central California coast has returned to full power after a two-month refueling and maintenance project.

Pacific Gas & Electric took the Unit 1 reactor and the twin-reactor plant out of service on April 23.

The San Luis Obispo County Tribune (http://bit.ly/OmGqd3) says it was brought up to full power on Friday.

Utility spokesman Blair Jones said Tuesday that operators used the planned outage for refueling to replace control room equipment with new digital devices for better plant monitoring.

Diablo Canyon produces enough electricity to power more than 3 million homes.
